Detailed implementation manners

[0031] The following further illustrates the present utility model with reference to the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and implement it, but the embodiments given are not intended to limit the present utility model.

[0032] Embodiment 1

[0033] Referring to Figures 1 to 11 As shown, the present utility model provides a wire harness fixing device, which includes an installation carrier 1 and a wire clip 2. The wire clip 2 is fixed to the installation carrier 1 and is used for quickly clamping and fixing multiple groups of wire harnesses 3. The wire clip 2 includes a wire bundling frame 4, a limiting portion 5, a sealing portion 6 and a fixing portion 7. The wire bundling frame 4 allows the wire harness 3 to pass through. The sealing portion 6 and the fixing portion 7 are used to cooperate with the installation carrier 1 to achieve reliable fixing and sealing effects. The wire harness fixing device has good wire bundling effect, is convenient for quick operation, can meet the refrigerant demand, and has good sealing performance.

[0034] Specifically, referring to Figures 1 to 5 As shown, the wire bundling frame 4 includes a wire bundling main body 41 and an opening and closing portion 42. The wire bundling main body 41 and the opening and closing portion 42 enclose a containing area 43 for threading the wire harness 3. One end of the opening and closing portion 42 is connected to one end of the wire bundling main body 41, and the free end of the opening and closing portion 42 forms a detachable connection with the other end of the wire bundling main body 41. When the free end of the opening and closing portion 42 is separated from the wire bundling main body 41 after disassembly, the free end of the opening and closing portion 42 and the wire bundling main body 41 form an opening 44 for placing the wire harness 3, and the wire harness 3 enters the containing area 43 from the opening 44. When the free end of the opening and closing portion 42 is connected to the wire bundling main body 41, the wire bundling main body 41 and the opening and closing portion 42 form a closed circular structure located on the outer periphery of the containing area 43 with the head and tail connected, and the opening and closing portion 42 is used to close the containing area 43.

[0035] It should be noted that through the research of the inventor of this case, it is found that most of the existing wire clips for wire harnesses used in refrigerants are set as wire frames and closed rubber parts for closing the wire frames. The plane where the rubber parts are located is perpendicular to the extension direction of the wire harness. The rubber parts have cross or cross-shaped notches and are opened in a petal shape for fixing the wire harness and dust prevention. On the one hand, this wire bundling structure is not suitable for fixing multiple groups of wire harnesses. The area where the petal-shaped rubber parts can open to achieve a tight wire bundling effect is very limited, and it is extremely easy to age and fail when fixing a large number of wire harnesses. And because the wire frame is a closed structure, the wire harness can only pass through the opening area from one side of the thickness direction of the rubber part, resulting in inconvenient installation and difficult maintenance. On the other hand, this wire bundling structure can only achieve simple dust prevention and cannot meet the sealing requirements in air conditioners. Similar problems also exist in the existing cable ties and other wire protection clips. Therefore, the wire harness fixing device of the present utility model is provided with an opening and closing portion 42 to form an opening 44, which is convenient for placing or taking out the wire harness, reduces the maintenance difficulty, and improves the operation efficiency, and is especially suitable for the fixing occasion of multiple wire harnesses.

[0036] Specifically, referring to Figure 4As shown, the end of the opening and closing part 42 away from the free end in the extending direction forms a bendable connection with the wire bundling body 41, and the connection part between the two is set as a thinning area 45; the size of the opening 44 is controlled by the bending angle of the opening and closing part 42, and bending through the thinning area 45 has higher durability than opening relying on material elasticity, is not easily damaged, and enables the wire clamp 2 to have a longer service life.

[0037] Further, referring to Figure 4 and Figure 5 As shown, in a preferred embodiment of the present utility model, the wire bundling frame 4 is set as a rectangular frame; in other embodiments, the shape of the wire bundling frame 4 can also be set according to actual needs, not limited to this. The rectangular frame is simple to process and can better fit the installation carrier 1. The wire bundling frame 4 has a set of relatively short short sides arranged oppositely, and a set of relatively long long sides arranged oppositely; the opening and closing part 42 is located on at least one set of long sides of the rectangular frame, and can provide a longer opening and closing part 42 compared with being set on the short sides, thereby providing a larger opening 44 for the wire harness 3 to be installed.

[0038] Preferably, one end of the opening and closing part 42 connecting the thinning area 45 is located on the long side, the free end of the opening and closing part 42 connects the end of the short side, and the extending length of the opening and closing part 42 is greater than half of the long side; the wire bundling body 41 is located on two sets of short sides, the other long side, and at least part of the area of the long side where the opening and closing part 42 is located. A larger extending length of the opening and closing part 42 can form a larger opening 44; compared with setting the entire long side as the opening and closing part 42, the wire bundling body 41 on this long side can also play a limiting role to prevent the wire harness 3 that has entered the accommodating area 43 from slipping off when the opening and closing part 42 is opened.

[0039] Further, referring to Figure 1 As shown, the wire bundling frame 4 is a bent plate member, and the plate member has a certain width in the axial direction of the extension of the wire harness 3 to provide guidance and fixation for the wire harness 3; the wire clamp 2 further includes a limiting part 5, and the limiting part 5 is at least arranged on the long side where the opening and closing part 42 is located, the limiting part 5 extends along the radial direction of the wire harness 3, and the limiting part 5 is perpendicular to the side wall of the wire bundling frame 4, that is, the surface of the plate member; a reinforcing rib 51 for increasing structural strength and extending service life is also connected between the limiting part 5 and the wire bundling frame 4. After the wire clamp 2 completes the wire harness fixing operation, the opening and closing part 42 is closed, and the long side where it is located needs to be pressed and fixed with structures such as a sealing plate to form a sealing edge and cooperate with the air duct to meet the refrigerant requirements.

[0040] Continuing, referring to Figure 4 and Figure 5As shown, the limiting portion 5 forms a pair of inclined surfaces 52 arranged opposite to each other on both sides of the thinning area 45, and the pair of inclined surfaces 52 are spliced ​​to form a notch of a "V"-shaped structure. Preferably, the pair of inclined surfaces 52 are symmetrically arranged. When the opening and closing portion 42 is opened, it rotates and bends around the thinning area 45 in a direction away from the accommodating area 43, and the pair of inclined surfaces 52 approach each other accordingly. When the pair of inclined surfaces 52 abut against each other, the opening and closing portion 42 is limited and cannot continue to rotate. The inclined surfaces 52 of the limiting portion 5 can control the size of the opening 44 of the line card 2, which not only reserves enough space for the installation of the wire harness, but also avoids excessive bending that affects the life of the thinning area.

[0041] Specifically, refer to Figures 1 to 3 , Figure 10 The free end of the opening and closing portion 42 is provided with a buckle 46 toward the cable harness body 41, and the cable harness body 41 is provided with a slot 47 for cooperating with the buckle 46; the end area of ​​the buckle 46 for extending into the slot 47 is provided with a wedge-shaped structure, and the inner wall of the slot 47 is provided with a locking portion 4701 near the notch, and the locking portion 4701 also has a locking slope for facilitating the passage of the buckle 46, and the tip of the wedge-shaped structure extends into the slot 47, and the wider end of the wedge-shaped structure forms a buckle step 4601 which is limited by the locking portion 4701. Figure 6 and Figure 7 As shown, when installing the wiring harness 3, it is passed through the opening 44 formed by the opening and closing portion 42 into the accommodating area 43, and the opening and closing portion 42 is rotated to fix the buckle 46 in the slot 47; when disassembling the wiring harness 3, force is applied to pull out the buckle 46 to disengage it from the slot 47, and the opening and closing portion 42 is rotated to remove the wiring harness 3 from the opening 44.

[0042] Specifically, refer to Figure 11 As shown, in some embodiments, the harness fixing device further includes an elastic member 8, which is located in the accommodating area 43 and is arranged to be attached to the inner side wall of the harness frame 4. Preferably, the elastic member 8 is configured as a sponge, and the elastic member 8 is bonded to the harness frame 4; the elasticity of the sponge can fill the gap between the harnesses, adjust the accommodating area 43, squeeze and fix the harness 3 inside, avoid collision and friction between the harnesses, and achieve a waterproof sealing effect.

[0043] Specifically, refer to Figure 9As shown, the mounting carrier 1 has a first surface 11 and a second surface (not shown in the figure) oppositely arranged in its thickness direction, and its thickness direction is parallel to the extending direction of the wire harness 3; the mounting carrier 1 is fixedly connected to at least three side edges of the wire bundling frame 4 except the long side where the opening and closing part 42 is located, and the three side edges of the wire bundling frame 4 cooperating with the mounting carrier 1 are provided with mounting parts and a sealing part 6; the mounting parts and the sealing part 6 are the same as the limiting part 5, and are all perpendicular to the surface of the wire bundling main body 41. The mounting parts and the sealing part 6 are respectively fixed on both side surfaces of the mounting carrier 1 in the thickness direction: the sealing part 6 abuts against the first surface 11, the fixing part 7 abuts against the second surface, and the sealing part 6 and the fixing part 7 form a gap in the thickness direction of the mounting carrier 1 to cooperate with the mounting carrier 1.

[0044] Further, referring to Figure 3 , Figure 9 and Figure 10 As shown, the sealing part 6 forms a sealed connection with the first surface 11 of the mounting carrier 1; the sealing part 6 has an abutting surface 61, and a convex block 62 is arranged on the abutting surface 61; the abutting surface 61 is closely arranged against the first surface 11, and the first surface 11 also has a groove 13 for clamping the convex block 62. Preferably, the convex block 62 is located at the center of the abutting surface 61, and the abutting surface 61 serves as an extended area around the convex block 62 to closely contact the first surface 11 to prevent liquid leakage at the connection between the convex block 62 and the groove 13.

[0045] Further, referring to Figure 2 and Figure 3 As shown, the fixing part 7 and the sealing part 6 are arranged at intervals on the outer periphery of the wire bundling main body 41, so that the two sides are evenly stressed when the wire clamp 2 and the mounting carrier 1 are fixed, and better fixing and sealing effects are achieved. Preferably, four groups of the sealing part 6, the convex block 62 and the groove 13 are provided.

[0046] Further, referring to Figure 3 and Figure 9 As shown, an installation seat 12 is also closely arranged around the outer periphery of the wire bundling main body 41 of the mounting carrier 1 for reinforcement; the wire clamp 2 is also provided with a triangular plate 9, and the triangular plate 9 is located at the bending part of the wire bundling main body 41 and is flush with the fixing part 7, and is used for fixing and sealing on one side of the second surface.
